HOPPER TEMP SENSOR (OPTION) (figure 29)
The hopper temp sensor thermal switch can be reset,
which is located in the hopper filter compartment near the
vacuum fan intake.
The temp sensor switch monitors the hopper air tempera-
ture near the vac fan. When the temperature of the air
moving through the hopper exceeds 140°F the temp
switch trips which turns off the dust control fan and
illuminates the hopper temp light on the warning bank.
When this occurs carefully investigate for a possible fire in
the hopper.
To reset the temp sensor, press the reset button. The
sensor will not manually reset until the temperature in the
hopper has dropped below 133°F.
VIBRATION ARM FOR LOWER FILTER(figure 30)
The vibrating arm is located on the clean side of the filter,
attached to the shaker pivot assembly. The purpose of the
vibrating arm is to move all dust that is shaken form the
filter into the dumping area by vibrating a plate located
directly below the filter. This is done by transmitting the
vibration of the shaker frame through a gland nut with a
bolt that is hammered by the vibrating arm.
For best results, the arm should be set up so that there is
a bout 1/32” to 1/16” clearance between the bolt and the
arm. This can be adjusted in many ways, by the position-
ing of the paddle on the shaker motor plate, adjustment of
the lift and turn latch, or if these are all set properly and
adjustment is still needed, you can bend the arm to get
the proper adjustment.
The arm and the gland nut are factory set, they should
only need inspection and/or adjustment when the arm
does not vibrate or hammer the bolt. When changing the
filter, inspect or adjust the arm at that time.
LOW OIL SHUTDOWN
The machine is equipped with a protection circuit to shutdown the engine when the oil pressure drops approxi-
mately below 5 psi. The Engine Oil Pressure light on the warning bank will illuminate as an indicator to the
operator.
Use the dipstick to check the oil level and add oil to the engine as needed until the oil is brought up to the
correct level.
